Issue also seems to occurs with 7.1.1 (`dmesg -f kern` output attached).
The DisplayPort to HDMI dongle does not have markings on the body to
identify the exact model, but by the looks of it I think it might be a
Vention HBKB0, which seems to be marketed as "1080p@60", "DP male to
HDMI female", "classic" (as opposed to "4K"). According to some
materials, the chip inside is a MXP3361.
The text on the HDMI cable reads "ULTRA HIGH SPEED HDMI™ CABLE -
WWW.HAMA.COM - HAMA GMBH & CO KG 86652 MONHEIM/GERMANY - 82623".
Reverting commit fee50077656 ("drm/amd/display: Bump the HDMI clock to
340MHz") on top of v7.1.1 appears to resolve the issue, as I am now able
to get a picture.
